METHOD OF MEASUREMENT OF THE PRESSURE IN HYDRAULIC AND PNEUMATIC SYSTEMS WITH LASER BEAM APPLICATION

Abstract

In the paper, non-contact method of measurement of the pressure with laser beam application is described. Actual solution associated with the topic is shown. Theoretical background of the introduced method is presented in the form of the formulae connecting load and geometrical deflection of the window, formula of the geometrical optics and law of the light absorption. Results of the experimental study confirm possibilities of presented method. Competitiveness of proposed method is demonstrated. Possibility of the application of the introduced method in different sections of the technique is presented.
